"We're going to go day to day," manager Bryan Price said. "It just wasn't good [today]. We'll see where he's at tomorrow and make that decision in the morning."

Left fielder Adam Duvall, who had been scheduled to get a day off, replaced Votto at first base and made an immediate impact, getting the Reds on the board with a two-run double in the first inning. He finished with two doubles and a walk in six plate appearances.
